CRYPT 1/15/79 CRYPT NAME crypt - crypt and decrypt standard input SYNOPSIS crypt key DESCRIPTION Crypt encrypts characters on the standard input by using 'key'. The file can eventually be decrypted by running it back through crypt with the same key. Double encryption (encrypting a file with first one key and then another) is allowable, but on some systems the decryption must be done in the exact reverse order as encryption was done. The encryption algorithm used by 'crypt' is not a complicated one, so users requiring a great degree of protection should not rely on this tool. FILES SEE ALSO DIAGNOSTICS AUTHORS Original from Kernighan & Plauger's 'Software Tools', with modifications by Debbie Scherrer. (NOTE: the original encryption algorithm has been altered slightly.) BUGS On IAS and VMS systems, double encryption must be decrypted in the exact reverse order as the encryption. -1-
